Definitions

  • the present invention relates to a method and apparatus for manufacturing paper cushioning members, and more particularly, to a method and apparatus for cutting a single sheet or plural sheets of work paper to be processed, such as unused paper or unnecessary newspaper, used copying paper, paper printed by an OA (Office Automation) equipment or used corrugated cardboard, to plural rows of thin intermittently-cut bands, stretching the resultant sheet or sheets of work paper to form a net, and crumpling the net-like sheet or sheets into an air-containing ball which has an adequate softness to thereby ensure continuous mass-production of such paper balls and permit the use of the paper balls as cushions or packings for transporting objects.
  • OA Office Automation
  • Another known cushion is a strong kraft paper processed to have short cuts and link portions by press working and then stretched to yield a fine almost beehive-like net.
  • the first type namely balls made of newspaper
  • the second type are soft to serve as good cushions, they are independent piece by piece and are easy to scatter, resulting in a lower working efficiency.
  • it is difficult to use the torn and crumpled pieces of paper directly they are normally placed in a paper bag or a poly bag when in use. If the bag is torn or broken, however, the crumpled pieces of paper undesirably come out of the bag through the torn section.
  • a method of manufacturing paper cushioning members comprising the steps of forming circumferential recesses and projections each of a given width on and around a surface of each of a pair of elongated roller members and engaging the recesses and projections of one of the roller members with those of the other roller member respectively; forming link-portion forming recesses each in a part of a circumferential surface of each of the projections in a horizontal direction or at a predetermined angle to the horizontal direction; inserting a single sheet or plural sheets of work paper to be processed between the pair of roller members and alternately forming cuts and link portions along the circumferential recesses and projections on the sheet or sheets of work paper, by using circumferential edges of the circumferential recesses and projections of the roller members; and stretching the sheet or sheets of work paper after alternate formation of the cuts and link portions in a direction perpendicular to a cutting direction, thus forming a net.
  • an apparatus for manufacturing paper cushioning members comprising a pair of elongated roller members having circumferential recesses and projections each of a given width thereon and therearound; cutting blades formed at peripheral edges of surfaces of the circumferential projections; and link-portion forming recesses formed each in a part of a circumferential surface of each of the projections in a horizontal direction or at a predetermined angle to the horizontal direction, whereby with the recesses and projections of one of the roller members engaged with those of the other roller member respectively, when a single sheet or plural sheets of work paper to he processed are inserted in the engaging portion between the roller members, cuts and link portions are alternately formed along the cutting blades by using circumferential edges of the circumferential recesses and projections of the roller members, and the sheet or sheets of work paper after alternate formation of the cuts and link portions in a direction perpendicular to a cutting direction, thus forming a net.
  • the apparatus according to the second aspect of this invention may be designed in such a way that the link-portion forming recesses are formed, all facing in one direction, in the circumferential projections.
  • the apparatus according to the second aspect of this invention may also be designed in such a way that the link-portion forming recesses are formed in facing surfaces of those of the circumferential projections which are adjacent to each other.
  • the apparatus according to the second aspect of this invention may be designed in such a way that the link-portion forming recesses are formed entirely across the circumferential projections in a horizontal direction.
  • the apparatus according to the second aspect of this invention may further be designed in such a way that the link-portion forming recesses are formed entirely across the circumferential projections, inclined at a predetermined angle to a horizontal direction.
  • a container for paper cushioning members comprising a paper-retaining container body having an openable/closable cover; and a take-out port formed in a front or side of the container body and having such a size as to allow insertion of a hand, whereby processed net-like paper cushioning members obtained by forming cuts and link portions in each work paper to be processed are retainable in the container body with that side of the net-like paper cushioning members along a cutting direction facing perpendicular to the take-out port and a desired number of sheets of the net-like paper cushioning members can be pulled out through the take-out port, so that when each of the net-like paper cushioning members is pulled out, a net is formed.
  • reference numerals "1" and “2" denote a pair of elongated steel roller members whose shaft portions 11 and 21 at both ends supported on a frame F by means of bearings.
  • Cutting blades 1' and 2' are formed at the peripheral edges of the circumferential surfaces R of circumferential projections formed on the roller members 1 and 2.
  • Reference numerals "3" and “4" respectively denote rectangular, circumferential recesses and projections a given width (allowed to be about 5 mm), which are formed on each of the roller members 1 and 2.
  • the circumferential recesses 3 of one roller member engage with the circumferential projections 4 of the other roller member, while the circumferential projections 4 of the former roller member engage with the circumferential recesses 3 of the latter roller member.
  • Reference numeral "5" is a plate-shaped barrier provided on that side of the roller member pair 1 and 2 where work paper to be processed is to be discharged.
  • the barrier 5 is disposed in a box-shaped container 10 in such a manner that its forward and backward movements are adjusted via a shaft 52 by a spring 51.
  • Each projection 4 of each roller member has link-portion forming recesses 6 each formed in a part of its circumferential surface in the horizontal direction or at a predetermined angle ⁇ to the horizontal direction (about 1 to 10 degrees in Fig. 10).
  • the length L of each projection 4 and the length G of each link-portion forming recess 6 can be set arbitrarily; in the example of Fig. 1, the length L is set to 50 mm while the length G is set to 7 mm. In this case, when the link-portion forming recess 6 of one, reference projection 3 of the lower roller member 1 comes to the top, the link-portion forming recesses 6 of the adjoining projections 3 come to the bottom.
  • Fig. 1 illustrates the link-portion forming recesses 6 of the circumferential projections 4 of each roller member formed to all face in one direction.
  • the link-portion forming recesses 6 shown in Fig. 7 are formed in the opposite surfaces of the adjacent circumferential projections 4.
  • the link-portion forming recesses 6 in Fig. 9 are formed entirely across the circumferential projections 4 in the horizontal direction.
  • the link-portion forming recesses 6 in Fig. 10 are formed in the circumferential projections, slightly inclined at a predetermined angle ⁇ (about 1 to 10 degrees in the illustrated example) to the horizontal direction.
  • Reference numeral “7” denotes cuts formed in work paper P' at a given width W (5 mm in the illustrated examples) by the pair of roller members 1 and 2.
  • Reference numerals “71,” “72,” “73,” ... “7 n” denote link portions which link the associated cuts 7 together.
  • the cuts 7 and the link portions 71 to 7 n are set by the intermittent recesses of the circumferential recesses and projections 3 and 4 of the roller members 1 and 2 and the lengths between the intermittent recesses.
  • Fig. 5 shows two thin bands linked by single link portions 71, ..., 7 n
  • Fig. 13 shows three thin bands linked by two link portions 71 and 71, ..., 7 n and 7 n .
  • reference numerals "8" and “9” are gears, which are attached to the shafts 11 and 21 of the roller members 1 and 2 and are engaged with each other to transmit power. Power from a motor (not shown) is transmitted to one of the gears, 8, through a belt or a chain.
  • Alphabet "C” indicates a cutter provided on the work-paper supplying side of the roller members 1 and 2 to cut the work paper P', fed by those roller members 1 and 2, to a given length.
  • Reference numeral “15” denotes a box-shaped container for retaining processed, net-like paper cushioning members.
  • the container 15 has a take-out port 151 formed in the front to have such a size as to allow insertion of one hand, and retain many processed, net-like paper cushioning members with that side of the net-like paper cushioning members along the cutting length facing perpendicular to the take-out port 151.
  • the cutting blades 1' and 2' of a given width are formed on the roller member pair 1 and 2, the link-portion forming recesses 6 are formed in the circumferential surface R of each projection 4 in the same direction, and the recesses 3 and projections 4 of one roller member are engaged with the projections 4 and recesses 3 of the other roller member respectively.
  • a number of processed, net-like paper cushioning members P having those cuts and link portions are retained one on another in the container 15 through an openable/closable cover 152 at the top.
  • the net-like paper cushioning members P are retained with the lengthwise direction of the cuts 7 set perpendicular to the take-out port 151.
  • the cutting blades 1' and 2' of a given width are formed on the roller member pair 1 and 2, the link-portion forming recesses 6 are formed, facing each other, in the circumferential surfaces R of the adjoining projections 4, and the recesses 3 and projections 4 of one roller member are engaged with the projections 4 and recesses 3 of the other roller member respectively.
  • a number of processed, net-like paper cushioning members P having those cuts and link portions formed in this manner are retained one on another in the container 15.
  • a container 10 is provided on the discharging side of the roller members 1 and 2 as needed as shown in Fig. 12, the work paper P' is sent to the container 10, hitting against the barrier 5 in that container.
  • the barrier 5 is shifted backward by a set amount by the spring in accordance with the discharging amount and is held there. Then, the work paper P' on the feeding side is cut by the cutter C at a given length L.
  • a bottom plate 101 is opened around a hinge 102 to drop paper chunks P''.
  • a poly bag should be set below the barrier 5, so that the discharged, crumpled paper members will be retained in the poly bag, contributing to preventing the products from being stained.
  • the cutting blades 1' and 2' of a given width are formed on the roller member pair 1 and 2, the link-portion forming recesses 6 are formed across the circumferential surfaces R of the adjoining projections 4 in the horizontal direction.
  • the cutting blades 1' and 2' of a given width are formed on the roller member pair 1 and 2, the link-portion forming recesses 6 are formed in the circumferential surfaces R of the adjoining projections 4, inclined at a predetermined angle ⁇ to the horizontal direction.
  • a stack of sheets of ordinary work paper such as newspaper, used copying paper, or printed paper, can be processed together to provide a relatively large net.
  • the processed, bundles of net-like paper cushioning members when in use may be retained one on another in the units of 10 kg per bundle, making the transpiration and storage of the paper cushioning members convenient. Further, the cuts are widened to form a net by simply pulling a desired number of paper cushioning members out from the take-out port at the front of the container. The resultant nets have only to be crumpled with hands to continuously mass-produce cushions or packings with adequate softness.
  • the crumpled paper cushioning members When the net-like paper cushioning members intermittently cut by a pair of roller members are crumpled into paper chunks by the barrier, the crumpled paper cushioning members absorb a larger amount of air, so that the paper cushioning members become softer.
  • a mechanism for cutting the processed paper cushioning member, already intermittently cut by a pair of roller members, to a predetermined length may be provided to always produce paper cushioning members with the same volume and constant quality.
  • the link-portion forming recesses are formed, inclined at a predetermined angle with respect to the horizontal direction as shown in Fig. 14, the link-portion forming recesses obliquely come in contact with the recess surfaces of the associated link-portion forming recesses, preventing overstrain from being applied to the paper members.
  • This design suppresses the wearing of the blades and is very advantageous.
